Model is CAH4205awj, got the TS sheet here, thanks for the copy. Was brought to shop, codes 23 door failed to un lock, and 06 locked rotor.
Cleared all codes, put in service mode, did cycle test no problems. Ran full wash cycle NPF (no problem found.

Ship it home, it wont drain all water out, weak pump, got that figured out, but in service cycle, would not do the 7/3 agitate in cycle. Spins fine. Spin test also checks all good.

I pulled j-4 and it does the 50 rpm test fine, however pressing pause stop would not end the test, touned off, and it still did not stop. had to un plug.

Tested motor windings all good in the hood.

Tested the high low water level, dry test, good. Then I even added water manually in tub, low sensor worked, swithced to high sensor indicator, it also indicated.

So now I ask, how do the pcbs, controller signal, each other. The panel board, does it, is it responsible for telling the motor control board to agitate, or spin. Saw there is only one input to the motor board from the main panel control.

Does it send 5vac for agitate (as an example) and then maybe a 10 vac or dc signal to spin.

Once the motor controller gets its order, for french fries or hambugers, or a cold brew then it runs the system accordianly, unless of course a pop top has shorted out the fryer, or the grille burner, )(agitate or spin program)

I see the motor has three windings, center tap is white, assume it's netural, but also figure polarity is switched inside of motor board to make it reverse or go foward.

I want to eliminate motor leads as the problem, because they seem to be common, spin would not workey at all the three different RPMs IF there was a open or short.

so who is the master and how can I tell if the main board is sending a order, to agitate, and the slave Motor controller is not working or only when ever it wants to. The contol signal, out put , is that a variable signial or constant.

Oh it's working just fine at the moment, we know how that goes. Thinking about taking it down one of thes old Mississippi Gravel road for a country road trip. Target practice with the 7 Mag may be in order lol.
